researches)
........... thanks

You have to configure the pins of the FPGA to accept input. Then you can 
acquiere every format you want with nearly every interface you might 
have.

By the way: you should better know, on what interface and pins the image 
arrives to your FPGA.

Possible configurations you can find in the datasheets from Xilinx. For 
example:
http://www.xilinx.com/support/documentation/data_s...

Spartan-3A FPGAs support the following single-ended
standards:
• 3.3V low-voltage TTL (LVTTL)
• Low-voltage CMOS (LVCMOS) at 3.3V, 2.5V, 1.8V,
1.5V, or 1.2V
• 3.3V PCI at 33 MHz or 66 MHz
• HSTL I, II, and III at 1.5V and 1.8V, commonly used in
memory applications
• SSTL I and II at 1.8V, 2.5V, and 3.3V, commonly used
for memory applications
Spartan-3A FPGAs support the following differential
standards:
• LVDS, mini-LVDS, RSDS, and PPDS I/O at 2.5V or
3.3V
• Bus LVDS I/O at 2.5V
• TMDS I/O at 3.3V
• Differential HSTL and SSTL I/O
• LVPECL inputs at 2.5V or 3.3

Also you find the RAM. The largenst one has 576 KBit, meaning 72 KByte.
This should be sufficient to store a BMP image of 120 x 200 (RGB).
